Euphorbia sieboldiana
Euphorbia sieboldiana Euphorbiaceae
They are a perennial plant that grows at such sunny places as in the pool of the forests and the roadsides (Perennial plant takes several years to grow). Their name is expressed in Chinese characters as ‘Natsutodai’, they blossom the earliest in the spring among the same group of Euphorbiaceae. They say their appearance looks like an ancient tool of how to turn a light on the dish filed with oil fuel, and this is where their name derivation comes from. They grow a branch split into 5 at the root of the leaf and the pot-shaped flower blossom at the top. 2 leaves are open below the flower, and the bottom is surrounded with 4 secretory portions. A secretory portion is the organ that is nectariferous, which looks like a jaw of stag beetle with the sharp tip. The leaves are nearly triangular spatula-shaped or long elliptically-shaped about 3 to 6 cm long. When the leaves and stalks are cut and then they secrete out white juice, we need to be cautious about the toxic component which the juice contains because if we touch them, our skins are bitten with the tox.
